In fact, Simpson shared a "honeymoon" picture via Instagram Monday, which showed the svelte singer striking a sultry pose in a sunlit room. She also posted a photo of herself posing next to husband Eric Johnson, writing, "I love this man, our marriage, and everything in between." The 34-year-old newlyweds stuck their tongues out for a third picture, with Simpson captioning the silly shot, "Yummy."

Simpson and Johnson—already parents to Maxwell, 2, and Ace, 13 months—have put baby plans on the backburner. On Sunday, a barefaced Simpson posed with interior designer pal Kathryn Sykora's baby boy and made a revelation: "I love you Jack, but I do not want another!! #maxiandacedo," she wrote on Instagram.

It's easy to sympathize with Simpson, given that she got pregnant with her son just seven months after giving birth to her daughter. Due to the surprise pregnancies, the couple's wedding plans were delayed.

The "Irresistible" singer finally got to walk down the aisle in a $1.4 million wedding ceremony on July 5. "We've anticipated this for so long," the Carolina Herrera-clad bride said. "It was amazing to feel the love of everybody and to be able to have our babies and watch us say 'I do.' It's a moment you can't describe."

How did Simpson look when she made her entrance?

"She was all lit up and beautiful," Johnson said. "I think my heart was exploding a bit."
